Patent GB-719400-A (GB)
Title: Manufacture of microporous moulded rubber articles
Inventor: LANE FREDERICK HENRY
Filed: 1952-01-03
Abstract: Moulded microporous rubber articles are produced by spreading a rubber latex composition containing gelling and vulcanising agents on to a shaped plastic mass comprising a moist finely divided inert water-insoluble solid, gelling the spread composition, vulcanising the rubber while it is supported by the shaped plastic mass under conditions preventing evaporation of water from the composition, and subsequently separating the vulcanised article from the moulded plastic mass.  In the manufacture of battery separators the plastic mass which may be a stiff colloidal clay, or a paste-like mixture of water and chalk or whiting is extruded in the form of channelled strip, alternatively depressions may be stamped on it by a press. The strip is then treated with a coagulant such as aqueous aluminium sulphate or calcium sulphate or formic acid and is then spread with compounded latex.  The clay strip is then carried to a gelling chamber and the latex gelled and then covered with a strip of fabric and wound on to a flanged drum and the whole treated at 170 DEG  C. in an autoclave to vulcanise the rubber.  The clay is then washed off, and the rubber sheet flattened by gentle heating and then cut to size.

Title: Improvements in the manufacture of potassium bichromate and of sodium bichromate andthe production of normal sulphates of potassium and sodium
IPC: C01G37/14
Filed: 1920-01-05
Abstract: Sodium and potassium bisulphates are used to convert sodium and potassium chromates into dichromates; the normal sulphate produced is recovered by concentrating the solution before crystallizing out the dichromate.ALSO:Sodium and potassium chromates are converted into their respective dichromates by the addition of the corresponding acid sulphate.  For example, by adding sufficient potassium hydrogen sulphate in the form of a coarse powder to the hot solution of potassium chromate, all the latter is converted into potassium dichromate.  After filtering, the solution is concentrated, when potassium sulphate separates.  From the mother liquor, after all sulphate has been removed, potassium dichromate is obtained by crystallization.

Filed: 1943-01-08
Abstract: 565,703. Automatic control systems for high-frequency oscillators. STANDARD TELEPHONES & CABLES, Ltd. Jan. 8, 1943, No. 378. Convention date, Jan. 10, 1942. [Class 38 (iv)] Oscillation frequency.-An. oscillator is locked in synchronism with a source of periodic waves having a form dissimilar to waves of like frequency derived from the oscillator. A balanced detector circuit having one output terminal earthed supplies its output voltage to a reactance tube 1 or other frequency correcting means associated with the oscillator 2. As shown, a reduced frequency saw-tooth wave from the oscillator is applied to the grid of an amplifier 34, the output circuit of which applies balanced voltages derived from resistances 36, 37 to the anodes of two diodes D<SP>1</SP>, D<SP>2</SP>, the cathode of one of which is earthed, the cathode of the other being connected to an output conductor 25 to control the reactance tube. Equal resistances 26, 27, 17, 18 are connected in series across the anodes and cathodes of the diodes and to the respective junctions are connected the output terminals of a mains transformer 30. Variable resistances 13, 14 in the anode leads permit the amplitudes of the applied saw-tooth voltages, which are in opposed phase, to be balanced. A zero voltage output is obtained only when the positive portions of the combined voltage waves applied to the resistances 17, 18 have equal area, which occurs at a specified phase difference of 270 degrees. The conductor 25 receives a positive or negative voltage according to the sense and degree of displacement from this condition. A switch 33 permits suppression of the correcting voltage when desired.

Title: Improved means for removing pressed bricks from the press in which they have been formed
IPC: B28B13/02
Filed: 1956-01-06
Abstract: 808,980. Removing bricks, &c., from presses. WESTERN COUNTIES BRICK CO. Ltd., and STEDHAM, M. E. C. Jan. 2, 1957 [Jan. 6, 1956], No. 501 /56. Class 87(2). The feed carriage of a brick press has arms carrying pads or diaphragms subjected to fluid pressure whereby they are expanded at appropriate phases in the cycle of operation of the press to grip the bricks, lift them off the press table, advance them and lower them on a deliv ery conveyer. The carriage 10 advances to feed the mould cavity 29 with clay and in so doing enables a previously ejected brick 28 to be gripped between pads 26 on arms 11 which extend from the carriage 10 and have brackets 15 on which are trolley wheels 19. Valves operated by mechanism in synchronism with the movements of the press cause fluid pressure to pass through ducts or pipes 25 in or on the arms 11 and distend the pads 26 so as to grip the brick. The wheels 19 run on rails 20 (covered by a dust shield) which are so profiled that the carriage 10 is raised at the start of its travel and lowered again at the end, the fluid pressure then being released so that the pads 26 collapse and drop the brick on a table or conveyer. The arms and pads may be multiplied and the arrangement may be inverted i.e. the arms moving on rollers which are raised and lowered in due synchronism.

Title: Improvements in automatic stop motions for spinning machines in particular for jute spinning machines
IPC: D01H13/18
Filed: 1954-01-07
Abstract: 751,225. Stop mechanism. HARBECK, M., and STEFFEN, H. W., [trading as HEIDENREICH & HARBECK]. Jan. 7, 1954 [Jan. 10, 1953], No. 507/54. Class 120 (2). A device adapted to operate in conjunction with feeler mechanism which automatically interrupts the supply of material to a textile spinning machine upon breakage of a thread, comprises a driving shaft 1, a feed roller 3 freely mounted in adjacent relationship with a frictionally mounted detent ring 2 on the shaft 1, the detents 6 of the ring 2 being engageable by a stop lever controlled by the thread feeler (not shown), a spring ring 8 arranged in a concentric groove of the feed roller 3 and having between its two ends 9, 10 a pin 11 secured fast to the roller 3 and a collar 5 formed in one piece with the ring 2 and extending into an annular space between the ring 8 and the shaft 1 and split in such a way as to form a cage 12 within which a roller 4 is freely rotatable. The ring 8 is rebated at its inner surface adjacent its end 9 so as to form between itself and the shaft 1 a wedge-shaped cavity 7 which comprises a wedge surface 13 and a transitional rounded surface 14 so that there exists at the point P a minimum of free space between the surface 13 and the shaft 1. The ring 8 is also provided on its outer surface with a long recessed portion 15 such that when pressure is exerted outwardly on the surface 13 the ring 8 can spring outwardly. In Fig. 2 the device is shown in an uncoupled position. When the ring 2 is not held fast by the stop lever it is rotated by the friction of the shaft 1 and through the collar 5, the roller 4 is carried in the direction of the arrow a-b so that a clamping action is produced between the surface 13, the roller 4 and the shaft 1 so that the feed roller 3 is also driven through the pin 11. Should the detent ring 2 be held fast by the stop lever on actuation of the " knock-off " mechanism, then by the overtaking action of the roller 3, the roller 4 rotates out of the wedge angle into the position shown in Fig. 2 in which the coupling is released and the feed roller is locked against further rotation. Upon the occurrence of an overload on the feed roller 3, the roller 4 is rotated past the point P so that thereupon the coupling is released. In a second embodiment the spring ring 8 is formed as a continuous ring.

Abstract: 587,710. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. Jan. 8, 1945, No. 652. [Class 88 (ii)] In an electrical musical instrument having a plurality of tone generators and in which generators can be employed to provide partials of different notes, the harmonic content is made large at the bottom end of the scale, decreasing towards the middle and, if desired, again increasing towards the upper end. Where the generators cover eight octaves, the first two and a half octaves might have an odd harmonic development such as a Bourdon tone, the next three octaves have their harmonics reduced to give a Concert Flute or Tibia tone and the upper notes are as highly developed as possible. With this arrangement a pure tone would be available for normal playing and more brilliance is obtained by coupling higher octaves. Pedal keys employ the rich development of the lower frequencies.

A continuous crystallization process wherein a saturated solution is removed from the top of a crystallizer; is made unsaturated, together with the addition of feed liquor of higher concentration, by controlling the temperature; is again made saturated by adjusting its concentration and/or temperature in a saturator; and is thereafter passed upwardly through the crystallizer from the bottom thereof whereby part of the solute is crystallized and recovered, is characterized in that the time from when the solution leaves the crystallizer until it enters the saturator is not less than the time necessary for the solute to spontaneously dissociate completely into free molecules in the' solution, and the time from when the solution enters the saturator until it re-enters the crystallizer is not more than the time required for spontaneous association of the free solute molecules into fine kernals in the solution. Solutes whose solubility increases or decreases with temperature are suitable, e.g. CuSO 4  or Na 2 SO 4 , unsaturation being effected by heating or cooling respectively. The added feed may also be heated or cooled. The unsaturated solution may be kept in a vessel for a short time before passing to the saturator, in order to achieve full solute dissociation. The saturator may use heating (or cooling) with evaporation. Larger crystals of greater uniformity are stated to be obtainable, compared with other similar processes. Crystal size is adjusted by varying the times referred to through adjustment of solution concentration.
